FFSAR- Coastal

Fully Focused SAR Altimetry and Innovative River Level Gauges for Coastal Monitoring

Home | Documents | Products | Publications

FFSAR-Coastal is a project funded by ESA to apply the Fully Focused SAR altimetry processor on Sentinel-3 data and evaluate its potential to make a significant new contribution to coastal and estuarine monitoring systems. Innovative in situ water level gauges will be used for validation. Two different environments will be considered:

  • The Severn Estuary and river: A highly dynamic mixed tidal estuary environment, the confluence between a river and its estuary experiencing large tidal range and strong tidal currents.
  • The lower Rhone Delta and Camargue: A low lying, flat river delta and wetland environment, susceptible to inundation and rising water levels.

By studying these two very different environments, the potential applicability and benefits offered by FF SAR altimeter data in other coastal, estuarine and delta locations will be demonstrated.

Applications will focus on the benefits offered by the very high along-track resolution in water level and backscatter that can be provided through FF SAR processing. User agencies and groups from the two regions will be consulted to identify gaps and priorities for monitoring requirements. Time series will be provided by autonomous in situ microstation gauges, drone-mounted instruments will be used to provide water level profiles between the fixed locations and satellite tracks.

User Engagement Workshop 17th May 2022 (1300 BST / 1400 CET):

We are pleased to announce that we will be holding an online User Engagement Workshop on Tuesday 17th May at 1300 BST / 1400 CET. Through this workshop we hope to consult agencies and groups working along the coast from the regions of interest: Severn Estuary (UK) and Rhone Delta (France); to identify gaps and priorities for water level monitoring requirements.

Project activities

Task 1 (March 2022 to February 2023):
User Engagement and Application Road Map

  • Review with stakeholders to identify key issues and requirements.
  • Workshops to present project results and invite recommendations.
  • Development of proposals for implementing a long term solution to meet user needs, adding to existing networks.
  • The output will be a publicly available Application Road Map

Task 2 (March 2022 to February 2023): Fully Focused SAR processing and water level analysis

  • DTU will implement the FF SAR SMAP processor and apply to Sentinel 3A and 3B data over the two study regions (Severn Estuary in the UK, and the Rhone delta in southern France)
  • The processed FF SAR data will be validated against in situ data, and evaluated in terms of its ability to map small scale coastal features.
  • Outputs
  • Data Sets: data will be made available online via links on the project website
  • Technical Report: Validation and evaluation results will be provided in a Product Validation Report

Task 3 (March 2022 to February 2023): Installation and operation of microstations, drone campaign

  • VorteX.Io will install 2 micro-stations in each study region, as soon as possible to maximise the time series.
  • A drone survey will be carried out in each region to perform water surface measurements to link the in-situ data to the satellite tracks.
  • Outputs
  • Data Sets: Campaign data will be made available via links on the project website
  • Campaign Report: A Campaign Report will provide analysis of data and summarise the operations.

Meetings

Project Kick Off (March 2022): Planning and confirmation of project timetable
